In October last year, my cousin Phil Gisby and I published The Five Sons of Charlie Gisby, a little biography of our great-grandfather and his prodigy. In the course of last night, the book clocked up its 1,000th download on Amazon's Paid Kindle.Phil and I are smiling. In fact, every single one of those one thousand downloads has produced a little smile on our lips. Through the book, we wanted more people to know about our unusual surname and its derivation. And, boy, have we succeeded!So a thousand thanks from us to all those people who downloaded (and hopefully enjoyed) the book. But if you haven't downloaded it yourself and you want to know what all the fuss is about, here are the links to it on Amazon.co.uk and Amazon.com.
